style="text-indent:25px">防爆攝像機安裝位置對光線的選擇：室內(nèi)安裝時從光源來看有順光、逆光、側(cè)光等幾種安裝位置。順光是指光線照射方向和監(jiān)控防爆攝像機的視場方向一致，人員正面受光均勻，無陰影，色彩還原比較正常。不過如光線過于強烈，會嚴重損失主體的表面層次。逆光與順光相反，光線的投射方向和監(jiān)控防爆攝像機拍攝方向相反，其主要造型特點是被攝人物主體正面受不到光線照明，主體正面的照度和背景及遠景照度相差較大，主體正面的細節(jié)完全損失，面部發(fā)黑，無法進行人像特征的識別。側(cè)光較為常見，棗莊球形防爆紅外攝像機，棗莊球形防爆紅外攝像機，室內(nèi)安裝時多數(shù)側(cè)光環(huán)境。側(cè)光是光線的照射方向在人物主體的一側(cè)，這種光線使主體人物一半明亮，一半產(chǎn)生陰影，人物暗部層次會受損失，人物表面明暗對比強烈，色彩還原尚可。室內(nèi)安裝時應盡量避免選擇造成逆光出現(xiàn)的安裝位置，如無法回避可選用寬動態(tài)監(jiān)控防爆攝像機增加順光源。要注意強逆光時人像主體正面的照度和背景的照度對比遠遠大于現(xiàn)有任何寬動態(tài)監(jiān)控防爆攝像機的動態(tài)比。多數(shù)寬動態(tài)監(jiān)控防爆攝像機技術(shù)的實現(xiàn)增強了面部的細節(jié)，棗莊球形防爆紅外攝像機，但是無法比擬順光環(huán)境下的成像層次和細節(jié)。因此對這三種的選擇是非常重要的。防爆攝像頭的防護：避雷針較好距攝像機3-4米的距離。棗莊球形防爆紅外攝像機</p><div

style="text-indent:25px">高清防爆攝像機將是工業(yè)監(jiān)控的主流：百萬像素高清防爆攝像機所供給的視頻畫面是傳統(tǒng)模仿防爆攝像機時期所不能比較的，清晰度的進步，圖像視野的擴展，均為其較凸起的優(yōu)勢。一方面，從分辨率數(shù)值對照來看：分辨率對比中咱們能夠明白地看到，百萬像素高清防爆攝像機供給的畫面分辯率有著數(shù)倍于傳統(tǒng)防爆攝像機清晰度的優(yōu)勢。除了視頻畫面清晰度的高下以外，實際應用中還有一個很主要的要求，即視頻畫面的實時性，以PAL制式來看，需要達到25幀/秒的傳輸及播放幀率。當前市場上大多數(shù)百萬像素防爆攝像機在720P或1080P分辨率格局下均可能達到25幀/秒的高幀率傳輸及浮現(xiàn)，而達到2560×1920分辨率的超高清防爆攝像機大多還無法實現(xiàn)此種清晰度下的實時出現(xiàn)。延安球形防爆紅外攝像頭防爆攝像機維護：防爆監(jiān)視器暴露在空氣中，由于屏幕的靜電作用。</p><div

style="text-indent:25px">防爆攝像機的結(jié)構(gòu)：近紅外指波長為0.75～3.0微米；中紅外指波長為3.0～20微米；遠紅外則指波長為20～1000微米。由于紅外光屬于非可見光，肉眼無法看見它在空間的存在，因此以一種能發(fā)射紅外光的LED二極管紅外燈主動發(fā)射紅外光的形式被大量使用于要求具有隱蔽性的夜視監(jiān)控中，代替?zhèn)鹘y(tǒng)隱蔽性低的照明燈夜視監(jiān)控。紅外燈有不同的功率及715、850nm兩種波長，波長的不同決定了紅外燈照距和效果。防爆紅外攝像機主要由紅外燈板、鏡頭及攝像主板，還有防爆護罩構(gòu)成。各構(gòu)成部分在防爆紅外攝像機工作過程中都擔負者重要的作用。</p><p style="text-indent:25px">防爆攝像機在什么檔次呢？攝像機較低照度。較低照度是當被攝景物的光亮度低到一定程度而使防爆攝像機輸出的視頻信號電平低到某一規(guī)定值時的景物光亮度值。一般彩色防爆攝像機的較低照度為2～3LUX，照度的測定是以在一定的鏡頭光圈系數(shù)為前提，因此，不能只看防爆攝像機說明書中標明的較低照度，應按防爆攝像機在同一光圈系數(shù)下其照度值的大小。較低照度越小，防爆攝像機檔次越高。相對于彩色攝像機而言，黑白攝像機由于沒有色度處理而只對光線的強弱（亮度）信號敏感，所以黑白防爆攝像機的照度比彩色防爆攝像機照度要低，一般可做到0.1LUX在F1.4時。防爆監(jiān)控攝像機的運行模式：旁路模式。</p><div

style="text-indent:25px">防爆攝像機：防爆攝像機能夠用在易燃易爆等危險場所，如煤礦、石油廠、油庫、花炮廠等。防爆攝像機的攝像部分一般安裝在現(xiàn)場,它包括攝像機、鏡頭、防爆護罩、支架和電動云臺。它的作用是對監(jiān)視區(qū)域進行攝像并將其轉(zhuǎn)換成電信號。防爆攝像機分為彩色和黑白兩種，一般黑白攝像機要比彩色的靈敏度高，比較適合用于光線不足的地方，彩色攝像機可以增加紅外效果以實現(xiàn)夜間監(jiān)控，光線暗時紅外燈自動開啟實現(xiàn)彩色和黑白轉(zhuǎn)換，如果使用的目的只是監(jiān)視景物的位置和移動，可采用黑白攝像機；如果要分辨被攝像物體的細節(jié)，比如分辨衣服和景物的顏色，則采用彩色的比較好。防爆攝像機的規(guī)格可分為1/3〃、1/2〃和2/3〃等，安裝方式有固定和可轉(zhuǎn)動的帶防爆云臺二種。防爆攝像頭的防護：與普通視窗玻璃相比，防爆攝像機的隱形雨刷視窗玻璃具有排斥水、灰塵等性能。專業(yè)防爆云臺一體機哪家好</p><p style="text-indent:25px">防爆攝像頭圖畫含糊。有可能是鏡頭焦距沒調(diào)好。棗莊球形防爆紅外攝像機</p><p style="text-indent:25px">防爆攝像頭的原理與選用：隔爆型防爆攝像頭等于隔爆攝像儀防護罩+普通攝像機、鏡頭。這樣的話，只要尺寸合適，工程商就可以自由選擇內(nèi)置的攝像機、鏡頭，同時成本也降低了。對于以后的維護，也方便很多，斷電源即可開蓋取出攝像機、鏡頭。這樣的隔爆攝像儀防護罩通常以抗危險壓力和沖擊的大強度不銹鋼制成，極其堅固。質(zhì)量好的產(chǎn)品壁厚在5MM以上，比防彈級別的防暴攝像機有過之而無不及。很多情況下，不銹鋼外殼遠比鋁制外殼優(yōu)越，比如抗腐蝕性能。特別是火災情況下的生存能力要遠遠好的多。棗莊球形防爆紅外攝像機</p></p><br
